Even though this bug affects grub2, it still needs to be fixed in grub-legacy.

It's just an a bit strange way to preserve the `default saved' in case you want to revert that change. Actually I think the only change we need to make, is to remove the added 0 again on purge, when the boot GRUB 2 menu entry gets removed. -- Felix Zielcke Proud Debian Maintainer -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
